Hey bugman!
We have a few of these critters outside of our office building just hanging out in the bushes. I live in South Florida and this is my first time seeing this kind of bug. We’re not sure if it will be a moth or butterfly.
It is a white caterpillar with black spots and black spines. Any feedback would be greatly appreciated!
Thanks in advance

Zebra Longwing Caterpillar

Dear Amber K,
This distinctive caterpillar is a Zebra Longwing Caterpillar,
Heliconius charithonia, and some of the bushes outside your office building must have passionflower growing on them.  Adult Zebra Longwings are lovely brown and yellow striped butterflies with forewings nearly twice the length of the hindwings.  See BugGuide for additional information and images.

Hi! I would just like some clarification please! We noticed today that we had what appear to be bees flying in and out of a hole in the wall on our flat. We’ve lived here for years & it’s the first year we’ve noticed it. We’ve done googling and suspect them (it?) to be Masonry Bees but would love clarification as we’re both wimps when it comes to flying stinging things and would love to know where we stand for our own sakes but also that of the cats who seem to think the hole provides them with flying toys! And we obviously don’t want either to get hurt. It doesn’t look quite right for a masonry bee but doesn’t look like honey bees / bumble bees / hornets etc so we turn to your expertise! Thank you!

Drone Fly

Drone Fly

Dear Tofu K,
This is a harmless Drone Fly,
Eristalis tenax, and we were puzzled by your observations that is was “flying in and out of a hole in the wall,” and we learned something very interesting on Nature Spot where it states they can be observed:  “Virtually all year round. The female hibernates in buildings and crevices but will emerge on warm days in late winter, leading to it being seen in virtually every month of the year.”  Larval Drone Flies are known as Rat-Tailed Maggots.  More information is available on UK Safari.

Daniel,
Thank you for your prompt reply! I was expecting to wait a little while as the websites state you may have to.
Thank you for putting our minds at ease! I was concerned it was some beastly giant buzzing bee we were going to have to live with! And very “pleased” that they sometimes mimic bees – it means we’re not going completely crazy!
Glad you learnt something new about them too!

I live east of Berkeley California and have been finding these winged bugs around my hallroom bathroom. Are they flying termites?
Thanks for any help you can provide!

Dear Andy,
You have an image of a winged Termite Alate as well as Termite Damage.  You should get some professional assistance.  A leaky pipe may have played a part in your infestation.

Dear Regan,
This is a Cork-Lid Trapdoor Spider in the genus Ummidia, and despite it making your skin crawl, it is a harmless species.  The spots on the underside of the abdomen are quite distinctive.  You can see a matching image on BugGuide.
  Spring rains may have flushed it from its burrow.

Subject: Can you ID these and their nest
Location: Northern Texas

I found some of these nymph stage bugs on my Live Oak tree last year and then this year i found several of their nests on my trees and house. The 1st picture is from this year, one up close to the eaves of my house on the bricks as they were hatching out. The 2nd picture is of them on my tree last year. I could not find anyone to ID them so sadly, I did spray them. The 3rd one is the bugs I collected off the tree after I sprayed them. (Sorry for that but I thought it would be better to err than have destructive bugs around. ) I just need to know what they are and if harmful or helpful. It looks like there are about 100 or so per nest. Hopefully the pictures are useful. If you use a viewer that can zoom in they looked good on my PC. Thanks for your help.

Wheel Bug Hatchlings

Wheel Bug Hatchlings

Dear Dan,
We hope our response this year prevents a similar carnage to that from last year.  These are beneficial, predatory Wheel Bug hatchlings, and they will help keep your trees and garden free of unwanted insect pests, eliminating the need to use pesticides.  Wheel Bugs are Assassin Bugs, and most are beneficial, and exception being the Blood Sucking Conenose Bugs.  Some other Assassin Bugs are prone to biting humans, and though the bite is painful and may cause local swelling, it is not considered dangerous, again the exception being the Blood Sucking Conenose Bugs.  We very rarely get reports of Wheel Bugs biting.  Adult Wheel Bugs are large, somewhat prehistoric looking creatures with a coglike “wheel” on the thorax.

Daniel,
Thank you so much for the information and education.  I have seen a lot of the adult versions of these “armored wonders” around the house but never saw them in their early stages.  I must have found about 8 or 10 of these nests around, some already empty and I assure you now that I know what they are will not do them harm in the future.  I had contacted my agriculture agent about the adults I saw around and he informed me that they were beneficial insects but he could not identify the nest and nymph stages.
Thank you again for all your time and help.

Hi,
I’m from Portugal, and I live in a village where you can find a lot of this kind of bug. Usually they’re in windows or walls, and they barely move. Sometimes I see one and in the next day it is in the same exact place. They look like they have wings but I never saw it fly, even when you lightly touch them. But they move! They look like they have two really big needles (but thin) on the bottom but they look inoffensive.

Mayfly

Mayfly

Hi David,
This is a Mayfly in the order Ephemeroptera, and winged adults do not eat and only live a few days, long enough to mate and reproduce.  Larval nymphs are aquatic and they are known as naiads.  Since adults are weak fliers, they are generally found near the water source that spawned them, so we expect there is a sluggish stream or pond nearby.  The threadlike tails or cerci are not harmful.  See Encyclopedia Britannica for more information on Mayflies.

Yes, there is a water source nearby. Thank you for your answer! Keep up the good work!
